Subject: [PATCH v3 0/1] xhci: Some improvement for Etron xHCI host

To prevent the xHCI driver from printing a "Transfer event TRB DMA
ptr not part of current TD" error message when an error is detected
while processing the last TRB of an isoc TD:
  xhci: Correctly handle last TRB of isoc TD on Etron xHCI host

---
Changes in v3:
- Update subject and commit message
- Use error_mid_td instead of last_td_was_short to solve the problem, as suggested by Michal
- Link to v2: https://lore.kernel.org/all/20241028025337.6372-1-ki.chiang65@gmail.com

Changes in v2:
- Modify commit message
- Remove XHCI_NO_RESET_DEVICE/XHCI_NO_BREAK_CTRL_TD quirk flag
- Add XHCI_ETRON_HOST quirk flag, thanks for the suggestion by Michal
- Check device speed before invoking the workaround
- Add (xhci: Combine two if statements for Etron xHCI host)
- Add (xhci: Correct handling of one-TRB isoc TD on Etron xHCI host)
- Link to v1: https://lore.kernel.org/all/20240911051716.6572-4-ki.chiang65@gmail.com
